Can't resume movie, it's just freeze with "OutputPicture - timeout waiting for buffer" in log

Hi all,
I started experiencing an issue that when trying to resume a movie it just freeze for a very long time around 15 minutes until eventually it start playing.
In the kodi.log there are the following lines:

The same problem occurs on two of my Odroid N2 devices.
I don’t remember changing anything on my Odroid N2 recently.
The last change is on my Synology NAS: I have inserted there SSD NVME disks and configured them as cache drive. It was around 20 days ago and I’m not sure if I started experiencing this issue the same day when SSD disks has been set as cache, rather it started happening around 2-5 days ago.

What steps for pinpoint the root cause of this issue should I take?
I would like to avoid to remove SSD disks from NAS. Is it possible it is the root cause?

Running CoreELEC 20.2-Nexus.

[EDIT] Disabling add-ones one by one I was able to find the cause of this issue. It is Language Preference Manager version 1.0.2. When this addon is disabled no freeze when resuming a movie.
